Expand in-place iteration specialization to Flatten, FlatMap and ArrayChunks
This enables the following cases to collect in-place:
```rust
let v = vec![[0u8; 4]; 1024]
let v: Vec<_> = v.into_iter().flatten().collect();
let v: Vec<Option<NonZeroUsize>> = vec![NonZeroUsize::new(0); 1024];
let v: Vec<_> = v.into_iter().flatten().collect();
let v = vec![u8; 4096];
let v: Vec<_> = v.into_iter().array_chunks::<4>().collect();
```
Especially the nicheful-option-flattening should be useful in real code.
effects: Run `enforce_context_effects` for all method calls
So that we also perform checks when overloaded `PartialEq`s are called.

Do not erase late bound regions when selecting inherent associated types
In the fix for #97156 we would want the following code:
```rust
#![feature(inherent_associated_types)]
#![allow(incomplete_features)]
struct Foo<T>(T);
impl Foo<fn(&'static ())> {
type Assoc = u32;
}
trait Other {}
impl Other for u32 {}
// FIXME(inherent_associated_types): Avoid emitting two diagnostics (they only differ in span).
// FIXME(inherent_associated_types): Enhancement: Spruce up the diagnostic by saying something like
// "implementation is not general enough" as is done for traits via
// `try_report_trait_placeholder_mismatch`.
fn bar(_: Foo<for<'a> fn(&'a ())>::Assoc) {}
//~^ ERROR mismatched types
//~| ERROR mismatched types
fn main() {}
```
to fail with ...
```

This PR fixes the ICE we are currently getting "was a subtype of Foo<Binder(fn(&ReStatic ()), [])> during selection but now it is not"
Also fixes#112631

internal: simplify the removal of dulicate workspaces.
### Summary:
Refactoring the duplicate removal process for `workspaces` in `fetch_workspaces`.
### Changes Made:
Replaced `[].iter().enumerate().skip(...).filter_map(...)` with a more concise `[i+1..].positions(...)` provided by `itertools`, which enhances clarity without changing functionality
### Impact:
This change aims to enhance the duplicate removal process for `workspaces`. This change has been tested on my machine.
Please review and provide feedback. Thanks!

Refactor borrowck liveness values
This PR starts cleaning up `rustc_borrowck`, in particular around liveness values:
- refactors simple names that make no sense anymore: either referring to older structures using region elements, or to bitset containers and values.
- improves comments and fixes others
- removes unused return values and unneeded generic arguments

fix: add fallback for completion label details
This PR adds a fallback to a previous implementation in a case when the label detail field isn't supported by LSP client and the support isn't reported by the LSP initialize request. In this case additional info about trait and aliases would be merged into the label field as it was before the #15956 PR.
feat: make `let_binding_suggestion` more reasonable
This is my first PR for rustc, which trying to fix https://github.com/rust-lang/rust/issues/117894, I am not familiar with some internal api so maybe some modification here isn't the way to go, appreciated for any review suggestion.
editor/code: add option to suppress error notifications
Fixes https://github.com/rust-lang/rust-analyzer/issues/14193
- Added the `rust-analyzer.showRequestFailedErrorNotification` configuration option, which defaults to `true`
- If `rust-analyzer.showRequestFailedErrorNotification` is set to `true`, the current behavior is preserved.
- If `rust-analyzer.showRequestFailedErrorNotification` is set to `false`, no error toasts will be displayed for any of the failed requests caused by panics in r-a. This _only_ applies to events that are triggered "implicitly", such as `textDocument/hover`.
To test this, you can manually introduce a panic in one of the language server LSP handlers for non-command events. I added an explicit `panic!()` in the `textDocument/hover` event handler:
#### `rust-analyzer.showRequestFailedErrorNotification` set to `true` (default)
[2023-11-07 17-17-48.webm](https://github.com/rust-lang/rust-analyzer/assets/1665677/d0408ab8-79d1-42cf-a4e7-94e99d9783ec)
#### `rust-analyzer.showRequestFailedErrorNotification` set to `false`

Fix tidy tripping up on untracked files with special characters in their name
Previously, the tidy tool would fault if an untracked file had a space or other special characters in its name. If there was an untracked file "foo bar", it would include the quoting in it's path and split on the first space, giving output like this:
`skip untracked path "foo during rustfmt invocations`
fix: Dedup duplicate crates with differing origins in CrateGraph construction
Partially fixes#15656 . Until now the condition for deduplication in crate graphs were the strict equality of two crates. One problem that arises from this is that in certain conditions when we see the same crate having different `CrateOrigin`s the first occurrence would be kept. This approach however results in some unwanted results such as making renaming forbidden as this has been recently only made available for local crates. The given example in #15656 can still not be resolved with this PR as that involves taking inconsistencies between dependencies into consideration. This will be addressed in a future PR.
Pass flags to `rustdoc` shim without env. vars
Discussed here: https://github.com/rust-lang/rust/pull/116448#issuecomment-1748785961. Since it was not really documented why these flags were passed through the shim, I guess that the only way to find out if it's really needed... is to remove it :)

kmc-solid: I/O safety
Adds the I/O safety API (#87329) for socket file descriptors in [`*-kmc-solid_*`](https://doc.rust-lang.org/nightly/rustc/platform-support/kmc-solid.html) Tier 3 targets. All new public items are gated by the `solid_ext` library feature.
This PR adds the following public types and traits:
std::os::solid::io::AsFd
std::os::solid::io::BorrowedFd
std::os::solid::io::OwnedFd
std::os::solid::prelude::AsFd (re-export)
std::os::solid::prelude::BorrowedFd (re-export)
std::os::solid::prelude::OwnedFd (re-export)
And trait implementations:
From<std::net::TcpListener> for std::os::solid::io::OwnedFd
From<std::net::TcpStream> for std::os::solid::io::OwnedFd
From<std::net::UdpSocket> for std::os::solid::io::OwnedFd
From<std::os::solid::io::OwnedFd> for std::net::TcpListener
From<std::os::solid::io::OwnedFd> for std::net::TcpStream
From<std::os::solid::io::OwnedFd> for std::net::UdpSocket
std::fmt::Debug for std::os::solid::io::BorrowedFd<'_>
std::fmt::Debug for std::os::solid::io::OwnedFd
std::io::IsTerminal for std::os::solid::io::BorrowedFd<'_>
std::io::IsTerminal for std::os::solid::io::OwnedFd
std::os::fd::AsRawFd for std::os::solid::io::BorrowedFd<'_>
std::os::fd::AsRawFd for std::os::solid::io::OwnedFd
std::os::fd::FromRawFd for std::os::solid::io::OwnedFd
std::os::fd::IntoRawFd for std::os::solid::io::OwnedFd
std::os::solid::io::AsFd for &impl std::os::solid::io::AsFd
std::os::solid::io::AsFd for &mut impl std::os::solid::io::AsFd
std::os::solid::io::AsFd for Arc<impl std::os::solid::io::AsFd>
std::os::solid::io::AsFd for Box<impl std::os::solid::io::AsFd>
std::os::solid::io::AsFd for Rc<impl std::os::solid::io::AsFd>
std::os::solid::io::AsFd for std::net::TcpListener
std::os::solid::io::AsFd for std::net::TcpStream
std::os::solid::io::AsFd for std::net::UdpSocket
std::os::solid::io::AsFd for std::os::solid::io::BorrowedFd<'_>
std::os::solid::io::AsFd for std::os::solid::io::OwnedFd
Taking advantage of the above change, this PR also refactors the internal details of `std::sys::solid::net` to match the design of other targets, e.g., by redefining `Socket` as a newtype of `OwnedFd`.
Make data reflect a case where dev deps are existent.
base-db::CrateGraph::extend now adds dev dependencies for a crate
in case of its upgrading from a CrateOrigin::Lib kind of a crate to a
CrateOrigin::Local one.
Partially fixes#15656 . When a crate graph is extended which is the case when new workspaces are added to the project
the rules for deduplication were too strict. One problem that arises from this is that in certain conditions
when we see the same crate having different `CrateOrigin`s the first form would be maintained. This approach however
results in some unwanted results such as making renaming forbidden as this has been recently only made available for
local crates. The given example in #15656 can still not be resolved with this PR as that involves taking inconsistencies
between dependencies into consideration. This will be addressed in a future PR.
